Description

Technical Field

[0001] The present invention relates to a mouth pad, and in particular to a multifunctional endoscope mouth pad. Background Art

[0002] With the continuous development of endoscopic technology and the continuous improvement of its accessories, gastroscopy and duodenoscope technology have become important examination and treatment measures for upper gastrointestinal and hepatobiliary and pancreatic diseases, such as early esophageal cancer, gastric cancer, common bile duct stones, acute obstructive suppurative cholangitis, bile duct injury, bile duct stenosis, and biliary complications after liver transplantation. Compared with traditional open surgery, this technology has the advantages of less trauma, high safety factor, and fast recovery. Endoscopic technology often uses oropharyngeal mucosal anesthesia or intravenous anesthesia. In order to facilitate intubation and avoid tooth damage to the endoscope, a mouth pad needs to be placed in the mouth before surgery; after the mouth pad and endoscope are placed in the mouth, breathing is affected in the open mouth state. In order to avoid the occurrence of hypoxemia, an oxygen tube needs to be worn before surgery for oxygen inhalation; under the stimulation of the endoscope, the oral mucosa and salivary glands will secrete a large amount of saliva, and the vomiting reflex will cause a large amount of gastric acid to reflux into the mouth, leading to aspiration.

[0003] At present, the mouth pad, oxygen tube and negative pressure suction tube are all used separately. The patient bites the mouth pad and fixes it to the back of the pillow through the elastic rope. The mouth pad is relatively fixed and rarely shifts. The tip of the oxygen tube needs to be inserted into the nostril and fixed behind the pillow through the upper edge of the auricle. During the endoscopic operation, the patient usually takes the side-lying position. The following deficiencies exist in clinical operation: 1. The head and face are pressed on the oxygen tube, and the tip of the oxygen tube is easily inserted too deeply or shifted to one side, damaging the nasal mucosa or causing a sneezing reaction, affecting endoscopic operation; 2. Under the action of gravity, the tip of the oxygen tube is easy to fall out of the nostril or shift, causing hypoxia in the patient, and the operation of adjusting or re-placing the oxygen tube during surgery is cumbersome, affecting the progress of the operation; 3. The oxygen tube is fixed to the occipital part above the auricle, affecting the fixation of the nasobiliary duct. The nasobiliary duct needs to be fixed after the oxygen tube is removed, which in turn affects the patient's oxygen inhalation; 4. The oxygen tube can only be supplied through the nasal cavity. Some patients have occlusion or are accustomed to breathing through the mouth, resulting in less nasal supply and absorption, and there is currently a lack of oral supply equipment; 5. The mouth secretes a large amount of saliva, and a large amount of gastric acid and bile will be vomited during vomiting. If the above-mentioned liquids are not drained smoothly or suction is not timely, it is easy to cause aspiration. The front guard of the mouth pad currently in use is equipped with a large saliva passage hole, but the saliva is relatively viscous and difficult to flow out on its own. If suction is not timely during the operation, it may lead to aspiration. This not only increases the clinical workload of the endoscopist, but also delays the progress of the surgical operation. Summary of the invention

[0004] According to the clinical operation proposed above, the head and face are pressed on the oxygen tube, and the tip of the oxygen tube is easily inserted too deeply or shifted to one side, damaging the nasal mucosa or causing a sneezing reaction, affecting the endoscopic operation; the tip of the oxygen tube is easy to fall out of the nostril or shift under the action of gravity, causing the patient to be hypoxic, and the operation of adjusting or re-placing the oxygen tube during the operation is cumbersome, affecting the progress of the operation; the oxygen tube is fixed to the occipital part above the auricle, affecting the fixation of the nasobiliary duct, and the nasobiliary duct needs to be fixed after the oxygen tube is removed, which affects the patient's oxygen inhalation; the oxygen tube can only be supplied through the nasal cavity, and some patients have Occlusion or habitual oral breathing leads to less nasal nutrition absorption, and there is currently a lack of oral nutrition equipment; the oral cavity secretes a large amount of saliva, and a large amount of gastric acid and bile will be vomited when vomiting. If the above-mentioned liquid is not drained smoothly or suction is not timely, it is easy to cause aspiration; the front guard plate of the mouth pad currently used is provided with a large saliva passage hole, but the saliva is relatively viscous and it is difficult to flow out by itself. If suction is not timely during the operation, it may cause aspiration. This not only increases the clinical workload of endoscopists, but also delays the technical problem of the progress of surgical operations, and provides a multifunctional endoscopic mouth pad. The present invention mainly adopts an integrated design of the oxygen inhalation tube, the negative pressure suction tube and the mouth pad, so that wearing and oxygen inhalation are more convenient, and the displacement of the oxygen inhalation tube can be avoided; the nasal cavity oxygen inhalation tube and the oral cavity oxygen inhalation tube are used to realize the simultaneous supply of oxygen through the nasal cavity and the oral cavity; by setting a silicone ring, a closed space is formed between the guard plate on the front side of the mouth and the skin around the oral cavity, so that the oral saliva and vomited bile, gastric acid and other liquids are sucked out in time to avoid the occurrence of aspiration.

Some patients have blockage or are accustomed to breathing through the mouth, resulting in less nasal absorption, and there is currently a lack of oral feeding equipment; the mouth secretes a large amount of saliva, and a large amount of gastric acid and bile will be vomited during vomiting. If the above liquids are not drained smoothly or suction is not timely, it is easy to cause aspiration; the front guard plate of the mouth pad currently used is equipped with a larger saliva passage hole, but the saliva is relatively viscous and difficult to flow out on its own. If suction is not timely during the operation, it may cause aspiration. This not only increases the clinical workload of endoscopists, but also delays the progress of surgical operations.
